Conservation of Cultural Heritage - Artificial ageing with simulated solar radiation of the surface of untreated or treated porous inorganic materials

This document assesses the long-term susceptibility to light of materials and treatments used in conservation of porous inorganic materials. Examples may include materials which have been treated in the course of conservation (e.g. cleaning, consolidation, water repellents, coatings or biocides) or materials which may exhibit colour changes following exposure (e.g. mortars and small number of stones). The procedure can be used to evaluate the impact and longevity/durability of treatments against untreated materials or unexposed materials.
NOTE 1   Porous inorganic materials are both natural stones (rocks) and artificial stone materials (mortars, stuccoes, bricks, ceramic materials, etc.).
NOTE 2   Treated materials are those on which one of the following treatments has been applied: cleaning, application of water repellent, consolidating materials, coatings or biocides and artificial ageing.

Erhaltung des kulturellen Erbes - Künstliche Alterung von unbehandelten oder behandelten porösen anorganischen Materialoberflächen mit simulierter Sonnenstrahlung

Mit diesem Dokument wird die Langzeit Lichtempfindlichkeit von Materialien und Behandlungen zur Konservierung von porösen anorganischen Materialien bewertet. Beispiele sind u.a. Materialien, die im Verlauf der Konservierung behandelt wurden (z. B. durch Reinigung, Konsolidierung, wasserabweisende Behandlungen, Beschichtungen oder Biozide), oder Materialien, die nach der Exposition Farbveränderungen aufweisen können (z. B. Mörtel und einige Steine). Dieses Verfahren kann angewendet werden, um die Auswirkung und Langlebigkeit/Dauerhaftigkeit von Behandlungen gegenüber unbehandelten Materialien oder Materialien, die keine Exposition erfahren, zu vergleichen.
ANMERKUNG 1   Poröse anorganische Materialien sind u. a. Natursteine (Felsen) und künstliche Steinmaterialien (Mörtel, Stuck, Ziegel, keramische Werkstoffe, usw.).
ANMERKUNG 2   Behandelte Werkstoffe sind Werkstoffe, bei denen eine der folgenden Behandlungen angewendet wurde: Reinigung, Einsatz von wasserabweisenden Produkten, Materialien zur Festigung, Beschichtungen oder Bioziden oder künstliche Alterung.

Conservation du patrimoine culturel - Vieillissement artificiel par rayonnement solaire simulé de la surface de matériaux inorganiques poreux traités ou non traités

Le présent document évalue la susceptibilité à la lumière des matériaux et traitements utilisés pour la conservation des matériaux inorganiques poreux, sur le long terme. Parmi les exemples, on peut citer les matériaux qui ont été traités en vue de leur conservation (à savoir nettoyage, consolidation, application d’agents hydrofuges, revêtements de surface ou biocides) ou les matériaux qui peuvent être sujets à des changements de couleur après exposition (par exemple mortiers et petit nombre de pierres). La procédure peut être utilisée pour évaluer l'impact et la longévité/durabilité des traitements vis-à-vis des matériaux non traités ou non exposés.
NOTE 1   Les matériaux inorganiques poreux concernés englobent aussi bien les pierres naturelles (roche) que les matériaux de type pierre artificielle (mortier, stuc, brique, céramique, etc.).
NOTE 2   Les matériaux traités concernés sont ceux qui ont subi l'un des traitements suivants : nettoyage, application d'un agent hydrofuge, de matériaux de consolidation, de revêtements de surface ou de biocides, et vieillissement artificiel.

Overview

SIST EN 17036:2018 is a European standard developed by CEN focusing on the conservation of cultural heritage, specifically targeting the artificial ageing of porous inorganic materials through simulated solar radiation. The standard provides a precise methodology to evaluate the long-term susceptibility to light of both untreated and treated porous inorganic materials commonly found in cultural heritage objects. These materials include natural stones like rocks, as well as artificial stone products such as mortars, bricks, stuccoes, and ceramics.

This standard is essential for conservation scientists and professionals aiming to test the durability and longevity of various conservation treatments-ranging from cleaning agents, consolidants, water repellents, coatings, to biocides-by subjecting materials to controlled and repeatable artificial solar radiation. It enables systematic assessment of effects such as color changes or material degradation due to light exposure, contributing to informed decisions about the most appropriate conservation methods.

Key Topics

• Artificial Ageing Technique
  SIST EN 17036:2018 outlines the use of artificial ageing by simulated solar radiation, favoring well-controlled variables over naturally variable weathering. It uses sources such as Xenon lamps combined with filters to replicate daylight's spectral distribution while limiting infrared and ultraviolet-B radiation.

• Test Equipment Requirements
  The standard details necessary equipment including:

  • Radiation sources simulating solar spectrum
  • Infrared (short-pass) and ultraviolet (long-pass) filters
  • Radiometers for precise irradiance measurements
  • Exposure racks ensuring uniform light distribution
  • Temperature control systems maintaining specimen surface temperature close to 40 ± 2 °C

• Test Procedure
  Specimens-often prepared with flat surfaces and minimum size requirements-are exposed to controlled irradiation for prescribed durations. Results are recorded as a function of radiant exposure (J/m²), allowing comparison across different setups.

• Evaluation and Reporting
  The standard provides clear guidance on documenting test conditions, specimen details, treatment types, equipment settings, environmental parameters (temperature, humidity), and resulting material changes. This ensures reproducibility and consistency.

Applications

SIST EN 17036:2018 is invaluable within the cultural heritage conservation field, especially for:

• Assessing Conservation Treatments
  Testing waters, consolidants, coatings, and biocides to predict their stability and colorfastness under light exposure before applying on invaluable heritage assets.

• Material Selection
  Comparing treated versus untreated porous inorganic materials to decide suitable conservation strategies for stonework, historic bricks, ceramics, and mortars.

• Quality Control and Research
  Supporting conservation scientists and manufacturers in developing durable materials with long-lasting performance when exposed to sunlight or indoor lighting conditions.

• Preventive Conservation Planning
  Informing exhibition lighting choices and environmental controls for heritage display settings.

Related Standards

Users of SIST EN 17036:2018 should consider familiarity with related standards and technical guidelines in cultural heritage conservation:

• EN 16085: Methodology for sampling cultural property materials prior to testing
• EN 13373: Determination of geometric characteristics of natural stone units
• EN 15898: General terms and definitions for conservation of cultural property
• EN 16581: Laboratory test methods for evaluating water repellent products on porous inorganic materials
• CEN/TS 16163: Guidelines for lighting conditions in indoor exhibitions to minimize deterioration

Further reference to international guidelines such as ISO 21348 (solar irradiance determination) and resources on accelerated ageing enhances understanding and application of this standard.

By implementing SIST EN 17036:2018, conservation professionals gain a robust, standardized approach to simulate and assess the durability of porous inorganic materials under solar radiation, enabling protection and preservation of cultural heritage with scientific rigor and confidence.
